BdOT-TREEING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 230,601, dated August 3, 1880.

Application filed April 1'7, 1880. (No model.)

To all whom it may concern:

Be it known that 1, JAMES A.'AMBLER, of Natick, county of Middlesex, State of Massachusetts, have invented an Improvement in Boot-Treeing Apparatus, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to boot-treeing appatus, and has especial reference to the construction of the rotating tree-carrying table or bed and its support, whereby the expanding-rods used to expand the trees may be operated or withdrawn at suitable times.

In this plan of my invention the rotating table is shown as provided with depending ears to support the fulcra of the levers, shown as elbow-levers, that withdraw the expandingrods, and the support for the rotating table is slotted or cut out, so as to permit the mechanism for operating the expanding-rods to pro ject below the table, travel with it during its rotation, and be free to be engaged temporarily or otherwise when it is desired to operate the said mechanism and expand the tree.

In an application filed in theUnited States Patent Office March 15, 1880, by myself and E. L. Wires there is shown a rotating table carrying a series of trees.

The trees in this present application, and the expanding devices within them, and means for introducing heated air or gas into the interior of the tree are and may be as in said application sothey need not be herein further described.

This present invention consists in such a construction of the table and its support as will readily permit the table to be rotated with the trees, and the expanding-rods to be drawn out by means of a treadle, lever, or other equivalent device controlled by the hand or oot.

Figure 1 represents, in side elevation, a boottreeing apparatus of the class described and shown in the application hereinbefore referred to, it being selected by me as one upon which to apply my present improvements. Fig. 2 represents a portion of the apparatus shown in Fig. 1 with my improvements added; and Fig. 3, a detail under side view, representing a part of the table-support and table and rolls.

The rotating table a has any suitable number of standards, b, to hold a suitable number of trees, g-such, for instance, as referred to in the said application.

The support a for the table a is shown as a bed cut away at its center, as at 0. to form an annular support, the space a serving to receive within it and permit the movement therein, in unison with the movement of the table, of the devices or means instrumental in operating the expanding-rods of the trees at the proper times. Inthis instance of my invention Ihave employed to operate the expanding-rods certain devices which are substantially like those now employed in ordinary boottrees for. like purposes. lever, b and a treadle, 0 This lever is pivoted'upon a depending portion, 1), of the standard b, and this portion is extended into or below and so as to travel with the table a without interruption. This lever has its short arm 12 adapted to be engaged by a hooked or other suitable connecting-rod, e suitably controlled port a the said rod 0 being shown as attached to a treadle, 0 The rod 6 is adapted to engage such lever 19 p only when the table in its rotation brings the lever opposite the said rod.

I have shown oneform of lever or mechanism for withdrawing the tree-expanding rod but it is obvious that the same might be changed in form without departing from the essence of my invention.

The table is adapted to rest directly upon rollers h having their journals held by the support ed, to facilitate its easy rotation, and attached to the underside of the table a. (see Fig. 3) are suitable rollers k on vertical axes. adapted to bear against andtravel over the inner wall of the annular support o to prevent lateral movement of the table a.

The upper end of the'lever p is herein shown as forked to embrace a grooved collar, 0, on the tubular expandingrod it; but instead of such collar I may employ a pinto be embraced by the upper end of the said lever, it being properly shaped. for that purpose.

1 claim tree-carrying table and connected devices to operate the expanding-rod, combined with the support for the table, cut away, as described,

by a guide, f fixed with relation to the sup- 1. In a boot-treeing apparatus, the rotating IOO the table, combined with a rod or link controlled by a guide and adapted to engage and actuate the expanding-rod-operating devices when brought into position opposite the said rod, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two 20 subscribing witnesses.
